SECTION 4: SERVICE MODE4.1 Introduction4.2 Service Level 1 4.3 Service Level 2

4.1 INTRODUCTION

The monitor supports a service mode built into the instruments firmware. To access the service mode, refer to Table 4-1: "Accessing Service Mode and Changing Parameter Settings".

The architecture of the monitors service mode divides the service mode into two levels as described in the sections below.

Service Level 1

Service Level 2

4.2 SERVICE LEVEL 1

The Service Level 1 provides information and tools on three service screens to test and calibrate specific functions without disassembling the monitor.

Information Screen

Event Messages Screen

Interface Test Screen

From these display screens the service technician can check the operating hours counter and event messages, test the Human Interface functions (HMI), set the light detection threshold, adjust the LCD contrast middle point and do a calibration check and a calibration process, if necessary. Refer to Table 4-1: "Accessing Service Mode and Changing Parameter Settings".

4.2.1 Information Screen

The information screen displays the monitors main board serial number, the number of operating hours, and the SpO2 and CO2 boards software versions.

4.2.2 Event Messages Screen

The monitor automatically performs a series of built-in tests (BITs) at start-up and during operation to check sub-systems and modules for errors. The event messages screen lists the last five event messages, the time each occurred relative to the units operating hours, and a recommended service action. There are three event messages and each has a specific response as follows:

Event Message: Action:

CO2 board Replace CO2 boardSpO2 board Replace SpO2 boardFlow Replace CO2 board

Section 4: Service Mode

4-2

Note: To exit the service mode and save event messages, turn off the monitor. Event messages will be erased when exiting the service mode by a long press of .

4.2.3 Interface Test Screen

The interface test screen shows four parameters (listed below) that provide tools for the user to test, adjust, and calibrate the units interfacing systems.

HMI Test

Light Detector

Contrast Cal. (Calibration)

CO2 Calib. (Calibration)

4.2.3.1 HMI Test

When the HMI Test is turned on, the monitor performs a self-test of the following sub-systems:

Buzzer (sounds for one second)

LCD graphic display (screen shows a checkerboard pattern)

7-segment digital display (8s scroll left to right)

Alarm bar (lights red, yellow, off)

Backlight (turns on and off)

Alarm silence indicator (light turns on and off)

When the HMI test is completed the status field returns automatically to OFF.

4.2.3.2 Light Detector

The Light Detector parameter allows the service technician to set the threshold value of the phototransistor. The default value is 1 and the range is from 1 to 5 with 1 as the most sensitive (backlight on at all times) and 5 as the least sensitive (backlight off). The threshold value should be set according to the lighting conditions of the working environment. A higher threshold value saves on battery power consumption.

4.2.3.3 Contrast Cal. (calibration)

The Contrast Cal. gives the service technician the option to change the middle point default value of the contrast intensity of the LCD. Refer to Table 4-1: "Accessing Service Mode and Changing Parameter Settings".
